My guess would be "probably not" but without proper scale and perspective, it's not possible to accurately identify their purpose.
Observations:
1. All three antennas appear to be identical Yagis cut to the same <unknown> frequency.
2. The two upper antennas are ganged to focus on one azimuth and are mounted for vertically polarized operation.
3. The lower antenna is horizontally polarized and aimed in a direction that appears to be about 30 degrees to the left of the upper pair.
Interesting....
